GPU: Graphics Processing Pnit, also occasionally called visual processing unit (VPU), is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the building of images in a frame buffer intended for output to a display. Their highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.

Nvidia is best known for its graphics processing units (GPUs). Nvidia and chief rival AMD Graphics Technologies (formerly ATI Technologies) have dominated the high performance GPU market, pushing other manufacturers to smaller, niche roles.
